Dear Uwe: 

      Thanks very much.  Based on your suggestion, I deleted 
"C:\\Users\\sgraves\\Documents/R/win-library/2.9", which got created 
when I first installed R 2.9.1 into the default, write-protected area 
and then did "install.packages".  When I uninstalled that 
write-protected copy and installed it in a different location, the 
directory "C:\\Users\\sgraves\\Documents/R/win-library/2.9" remained, 
and Rgui directed "install.packages" to that directory, though Rterm did 
not.  I had not intentionally set "R_LIBS" nor any other special thing 
like that, so I was confused. 

      Thanks again.
      Best Wishes,
